ELECTRICAL INSTALLATION

DANGER!
Make sure the AC power supply is disconnected
before starting the installation.
DANGER!
The following information is merely a guide for proper
installation. Comply with applicable local regulations
for electrical installations.
DANGER!
The inverter will be damaged in case the input power
supply is connected to the output terminals.
